PATENT JOHN HYSLOP, OF ABINGTON, MASSACHUSETTS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE UNITED SHOE MACHINERY COMPANY, A COR- PORATION OF NEW JERSEY.

APPARATUS FOR SHAPING HEADS OF NAILS.

SPECIFICATION formingoart of Letters Patent No. 687,687, dated November 26, 1901.

Application filed March 26, 1898. Renewed March 15, 1900. Serial No. 8,857. (No model.)

To ctZZ whom it may concern:

Be it known that I, JOHN HYSLOP, ofAbing ton, county of Plymouth, State of Massachusetts, have invented an Improvement in Apparatus for Shaping Heads of Nails, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

Much difficulty is experienced in the use of nailing machines employing loose nails because of the lack of uniformity in the heads of the nails, such variations in the heads causing lack of uniformity in the appearance of the work and also materially interfering with the proper delivery of the nails to be driven one by one. Many experiments have been made to overcome this difficulty arising from the variation in the heads of the nails.

I have devised an apparatus through which the loose nails to be used in nailing-machines for bootand shoe and like work may be passed preparatory, to putting them into the hopper of the usual nailing-machine.

My apparatus has been especially devisedto shear and shape the heads of the nails so that they are all left uniform in size and shape, so that when put into the hopper of the nailing-machine or the raceway of the nailing-machine they will feed uniformly and may be taken ofi without difficulty, and the work done will be uniform in appearance.

My improved machine contains a hopper to receive the nails in bulk, they being fed therefrom into a suitable raceway having a slot in which the bodies of the nails hang supported by their heads lying on the top of the raceway. On the arrival of a nail at the end of the raceway its head is permitted to pass onto a lifter, which lifts the nail above the level of the remaining nails back of it in the raceway, said nails during such operation being prevented from leaving the raceway by a suitable stop or device cooperating therewith, said device being located at the end of the raceway.

way by the nail-lifter is thereafter acted upon by a transferrer, it removing the nail laterally from the lifter and. putting it into a covered notch of a carrier, and the nail having A nail taken from the race- Y been deposited in said notch the carrier and the transferrer are moved bodily together to place the nail held between them in position in line with an opening in a pair of point centering or directing jaws and in line with a punch and die, and thereafter by a change in the relative positions of said die and punch thepoint of said nail is made to enter an opening in said jaws and also a hole in the top of said die, said hole being of the shape it is desired to give to the head of the nail. During this change in the relative positions of said die and punch, the body of the nail having entered the opening of the said directing-jaws and the opening in the die, the transferrer and carrier, yet holding said nail with its head under the punch, are separated,

leaving the centering-jaws holding the nail,

the point of the nail standing in the opening of the die, said dies and jaws continuing their upward movement to thereby put the head of the nail substantially against the punch, at which time the centering-jaws are opened, letting the die strike the under side of the head of the nail, and immediately thereafter the punch strikes the upper side of the head of the nail, so that in the continued upward movement of thedie, the centering-jaws being opened, the punch acts on the head of the nail and forces the said nail through the opening of the die. The nails, with their heads sheared to shape, drop one by one from the apparatus through a suitable chute or conductor into a receptacle placed for the purpose.

Figure 1 in front elevation shows an apparatus for shaping nail-heads, said apparatus embodying my invention. Fig. 2 is a righthand side elevation of the said machine, but on a smaller scale. Fig. 3 is a left-hand side elevation thereof. Fig. 3 shows the'upper end of the slide D with all the parts carried by it removed. Fig. 4 is an enlarged detail showing the carrier and oentering-jaws, anvil-die, and a part of the lower end of the 'head of the machine. Figs. 5 and 6 show the same devices, but in different operating positions. Fig. 7 shows one side of the nail-lifter. Fig. 7 is an opposite side view of the lifter h.

Fig. 8 shows the anvil-die and its holder.

ICO

Fig. 8 shows one of the blocks having the ears to support the head of the nail detached from the lifter. Fig. 9 is asection in the dotted line 00, Fig. 4, looking at the centeringjaws and the anvil-die. Fig. 10 shows the acting end of the nail-carrier. Figs. 11 to 15 show views of the operating parts in different positions, to thus illustrate, substantially, a cycle of operations. Fig. 16 shows a nail in the condition in which it is put into the hopper to have its head sheared, and Fig. 17 shows a nail with its head sheared.

The framework consists chiefly of a column A, carrying a head A, provided with suitable cam-shaft A having a balance-wheel A and suitable fast and loose pulleys A and A The hopper L, rotated by the belt 52 from the main shaft A and the inclined slotted raceway Nto conduct the said nails into position to be taken therefrom one at a time, as will be described, are substantially the same as illustrated in United States Patent No. 467,104, heretofore granted to me, and dated January 12, 1892, so said devices need not be herein further described.

The cam-shaft A has fast on it a suitable cam hub or hubs provided with suitable camgrooves, as B O. The cam-groove 0 receives in it a roller or other stud carried at one end of a lever O, pivoted at (J on the head, the upper end of said lever having joined to it a link C in turn joined to the upper end of a lever 0*, provided at its lower end with the transferrer a, said lever C being pivoted at ct. The cam-groove B receives in it a roller or other stud of a lever B, pivoted at B on the framework, the opposite end of said lever being joined by a link B in turn joined to the upper end of a lever 13*, provided at its lower end with a carrier 1) to be described, said carrier consisting, essentially, of a finger or plate having a notch at b and a groove at 12 the top of the notch being covered by a lip 5 the carrier being fastened to the lever B by a suitable set-screw b The rotation of the cam-shaft A causes the transferrer and the carrier to be moved toward and from each other at the proper times, as will be described.

The head of the machine is provided with suitable dovetailed guides A and D said guides receiving suitable dovetailed parts of a slide D, carrying the anvil-die and centeringjaws to be described. This slide D, which constitutes in practice a die-carrier, has its upper end reduced in width by cutting the same back from the corners d, Fig. 3 to the upright edges 01, and the upper end of the die is then further reduced by cutting away a portion of the upright, leaving notches at d", said notches being at each side of a projection d which constitutes the extreme upper end of the slide D, said extreme upper end having made through it a suitable hole, as 61 through which the nails, having their heads properly sheared, pass on their way into the delivery-tube (1 which leads the finished nails from the apparatus. The slide D may be reciprocated vertically by or through a roller or other stud d connected with said slide and shown in dotted lines in Fig. 1 and full lines in Fig. 2, said roller entering a camgroove (1 in the face of a cam-disk d fast on the main shaft A The notches (Z in the slide receive the lower ends e of the movable nailcentering jaws e, there being two such jaws, each being herein represented as pivoted on asuitable stud-screw 6 inserted in a threaded hole made in the upper end of the slide D at its rear side (see Fig. 9) above the shoulders at the bottom of said notches. Each of these jaws has an ear, as 6 provided with a suitable hole, in which is entered one end of a spring e said spring (best shown in Fig. 1) normally acting to keep the faces of said jaws normally closed, as best shown in Figs. at and 5, the said faces being provided each with a notch, as e the two notches together forming a passage-way for the body of the nail, the said jaws when open permitting the head of the nail to pass between them. These jaws are opened each time the slide D is elevated, for at that time the ears a meet the roller or other projection 2 connected with a stand a", suitably attached to the head A by suitable bolts, as 6 (See Fig. 2.) The head A has a depending projection A the extreme lower portion of which is somewhat reduced in size and is suitably bored to receive the shank of a punch f. The head has fastened to it at its left-hand side, as herein shown, by screwsf a suitable guidewayf in which is placed a slide-rod f said sliderod having a suitable studf which is extended out through a slotf in said guideway, said stud having fast upon it a suitable spiral or other springf, attached to a stud f on the guideway or other fixed part of the frame, said spring normally acting to keep the slidebar f down in its lowest position. The upper end of this slidebar is provided with a projection g, slotted to embrace an ear h, connected to the lifter h, (shown as detached in Figs. 7 and 7 the said ear being attached to said lifter by a suitable screw 7L inserted in a tapped hole of said lifter, said ear being located at that side of the lifter next the end of the raceway. The lifter at its lower end is slot= ted or cut away, as bestshown in Fig. 7, and in said slot I secure two blocks 72, it, said blocks each having a like tongue, as h h, one of said blocks and its tongue being shown at Fig. 8. Said tongues are extended from the front side of said lifter through the slot made therein, and the tops of said tongues, as shown much enlarged in Figs. 11 to 15, are somewhat concaved in shape, so that when said lifter is in its lowest position, as represented in Fig. 15, the upper edges of said ears will stand as a continuation of the top edges of the raceway N, so that the head of a nail may pass from the end of said raceway upon the upper ends of said ears. At this time the nail-head passes under the lower end of a lug h, fastened to the carrier 71. at its front side by suitable screws h the lower end of said lug bein g pref- .erably convexed to facilitate the passage of I to its right-hand side by suitable screws m a guide plate or box m, which receives in it a slide-bar m said slide-bar having connected to it in suitable manner a suitable spring, as m which normally acts to keep the said slidebar held in its forward position, and with the upturned nail-stop m of said slide-bar in proper position with relation to the end of the raceway, as shown in Fig. 15, to let a nail pass from the end of the raceway onto the tops of the ears of the lifter, the shank of said nail meeting the nail-stop m as in said figure. This spring m also serves to cause the roller or other stud m carried by the lever m pivoted at m and connected with said slide m in an adjustable manner against a face-cam m fast on the shaft A the said cam in the rotation of said shaft causing the slide-bar m to be moved back and forth, as will be described.

The extreme upper end (55 of the slide D receives upon it and sustains one end of a block at, in which is provided a suitable recess for the reception of the anvil-die it, held in place i by a suitable set-screw W, said die having a central opening a in its upper end, which will be of the shape which it is desired to give to the finished heads of the nails. This plate 'nhas depending from its lower side two suit able threaded rods a which are inserted through slots 01, in the projecting portion (Z at the upper end of the slide D, said threaded rods being passed through a thin plate 41 and thereafter they each receive a suitable nut, as a which serves to confine the plate and its anvil-die firmly in position.

Assuming that a nail has passed from the raceway upon the upper ends of the ears referred to carried by the lifter, as in Fig. 15, the lifter will be elevated by or through the sliderod f it having a suitable roller or other stud, as 0, which enters a groove 0, shown by dotted lines in the rear side of the cam d and as said lifter is elevated it will take the nail with it, as represented in Fig. 11, and at the same time the slide D will descend from the position Fig. 15 into its normal position Fig. 11. The lifterwill be raised until the upper ends of the ears come substantially opposite the opening I) of the carrier, said carrier in the meantime being moved to the right, viewing Figs. 15 and 11, into the position shown in Fig. 12, it passing under the punchf. On the arrival of the carrier and the lifter in the position shown in Fig. 12 the transferrer a, it having a narrow end capable of passing in between the slot left between the two cars k and it, will be moved to the left, viewing Fig. 12, and will strike the body of the nail suspended on the upper ends of the said ears, and will push the said nail laterally off from thenotch b and the body of the nail the slot 19 in the carrier, and the movement of the transferrer and the carrier will be continued uniformly together to the left, as in Fig. 13, until the point of the nail so clamped and held between the transferrer and carrier is placed over the opening 6 in the ends of the centeringjaws e,-as in'Fig. 13. Now at this time the slide D will be started on its upward movement, causing the nail-centering jaws to pass over the shank of the nail, and the point of the nail will also be made in this upward movement of the slide to enter the hole 11* in the die n, and about as the upper side of thejaws e arrive at the lower sides of the transferrer and carrier said transferrer and carrier are separated substantially into the positions Figs. 5 and 14, and the jaws continue in their upward movement, grasping frictionally between them the body of the nail, the point of the nail lying in the hole in the die. slide D continues to rise until the jaws arrive substantially opposite the lower end of the punch, at which time the parts 6 of said jaws meet theprojections e, which are to open the jaws, and immediately thereafter the head of the nail is forced against the punch, and in the continued rise of the die the head of the nail against said punch is forced through the die-opening, thus shearing the said head tothe desired shape.

Referring to Fig. 16, 9 represents the body of a nail, and 19 its head, the said head having at its extreme upper end a fin or projectionp These nails are made by machinery, and the heads are formed by cutting or upsetting the metal, and of course they are not all left exactly uniform in shape, so by passing this nail through the apparatus herein described the finp may be removed, leaving the body and head as substantially represented in Fig.17, and this head may be either circular or of other shape, according to the shape of the opening in the top of the die n. This invention is not limited to the particular taper or quantity of metal in the head part, (marked p,) although the shape herein. represented is a preferable one for nails of the class to be used in nailing-machines.

When the lifter rises from the position Fig. 15 into the positions Figs. 11, 12, and 13, the inclined side edges of the ears connected with the lifter, acting on the endmost nail of the series of nails in the raceway, crowd it and the nails behind it back slightly in the raceway, thus adjusting the nails correctly in the raceway, said edges also preventing any nails leaving the raceway, for the reason that the slot between the two lugs W and h is narrower than the diameter of the heads of the nails. However, as the lifter commences to descend from the position Fig. 13 into the position Fig. 14: the nail stop m is moved slightly to the right from the position Fig. 13 into the position Fig. 14, it act ing upon the endmo'st nail of the raceway and pushing it and its fellow nails next to it farther slightly to the right and slightly up the raceway, said stop keeping the said nails in such position until the lifter has again arrived into the'position Fig. 15, when the said stop is again moved to the left, letting the endmost nail follow it and pass onto the tops of the ears h and h. Fig. 15 shows the anvil or die in its highest position, the punch having acted upon the head of the nail, the latter being shown as leaving the opening in the die, leaving the shearing on the top of the die. Now as the lifter arrives again in its position Fig.-15 the slide D is lowered into its normal position, Fig. 11, and the lifter is again elevated, as before described.

By imparting to the slide m having the nail-stop m, a to-and-fro movement I am better enabled to control the delivery of the nails from the raceway than were the said stop fixed in the lower end of the raceway, as provided for in United States Patent No. 472,638, heretofore granted to me and dated April 12, 1892. That patent shows a lifter which closely resembles and is substantially the same in construction and operation, so far as it receives upon it the heads of the nails and lifts them, as the lifter hereinbefore referred to. That patent, however, did not comprise or contain any devices whatever for shearing the head of the nail.

This invention is not limited to the precise shape shown for the transferrer or the nailcarrier or the nail-stop so far as they are combined and cooperate with the punch and die, nor is this invention limited to the exact shape for the jaws for centering the nail between the transferrer and carrier and the opening in the die, and instead any other usual or suitable devices may be employed.

The plate or block a, carrying the die a, has a notch n (see Fig. 8,) in which enters the lower end of the carrier 1), as in Fig. 15, when the slide D arrives in its highest position.

The raceway is jarred or vibrated, so as to enable the nails to slide freely down it, by or through a suitable hammer, the handle 9" of which is pivoted at r, a suitable cam on the main shaft A operating said handle in one direction, a spring r operating it in the opposite direction.
